It is seen from a comparison of FIG. 15B with FIGS. 15A/1 and 15A/2 that whereas in FIGS. 15A/1 and 15A/2, in the first operative orientation, the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is closed, in the second operative orientation of FIG. 15B, the slidable engage/disengage point of sale terminal 100 is partially opened by the user grasping the slidable top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 710.

Whereas in the first operative orientation shown in FIGS. 15A/1 and 15A/2, as seen particularly at enlargements A, B and C thereof, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 504 thereof and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 616 thereof, in the second operative orientation shown in FIG. 15B, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof.

It is also seen that base portion 610 of first slidable pin element 410 (FIGS. 10A-10D) remains located at the outward end 518 of recess 514 formed in base portion 400.

Correspondingly, whereas in the first operative orientation shown in FIGS. 15A/1 and 15A/2, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 524 thereof and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 646 thereof, in the second operative orientation shown in FIG. 15B, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 644 thereof. Second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) remains located at the outward end 536 of recess 534 formed in base portion 400.

Whereas, as seen in FIG. 15A/1, particularly at enlargement D, downwardly directed tooth 566 lies in a valley defined between teeth 312 and 314 and downwardly directed tooth 564 lies inwardly thereof along cantilevered catch tab 310, outward displacement of inwardly-directed extension portion 560 to the second operative orientation shown in FIG. 15B, as particularly seen at enlargement D, causes downwardly directed tooth 566 to lie outwardly of valley defined between teeth 312 and 314 and downwardly directed tooth 564 to remain at a position inwardly of the valley defined between teeth 312 and 314. The disengagement of downwardly directed tooth 566 from valley defined between teeth 312 and 314 slightly flexes the cantilevered catch tab 310 and provides a user-sensible resistance which indicates to the user that the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is being opened.

Whereas, in the first operative orientation shown in FIGS. 15A/1 and 15A/2, registration pins 462 and 464 of base portion 400 are fully engaged in pin receiving registration sockets 181 and 182 at end 180 of main top housing portion 104, in the second operative orientation shown in FIG. 15B, registration pins 462 and 464 of base portion 400 are fully disengaged from respective pin receiving registration sockets 181 and 182 at end 180 of main top housing portion 104.

It is seen from a comparison of FIG. 15C with FIG. 15B that whereas in FIG. 15B, in the second operative orientation, the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is partially open, in the third operative orientation of FIG. 15C, the slidable engage/disengage point of sale terminal 100 is fully opened by the user grasping the top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 720, which is identical to the direction indicated by arrow 710 (FIG. 15B).

Whereas in the second operative orientation shown in FIG. 15B, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof, in the third operative orientation shown in FIG. 15C, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 504 and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof.

It is also seen that base portion 610 of first slidable pin element 410 (FIGS. 10A-10D) is now located at the inward end 516 of recess 514 formed in base portion 400 of slidable mounting assembly 122.

Correspondingly, whereas pin 302 in the second operative orientation shown in FIG. 15B of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 646 thereof, in the third operative orientation shown in FIG. 15C, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 adjacent end 524 thereof and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 644 thereof. Second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) is now located at the inward end 535 of recess 534 formed in base portion 400.

Whereas, as seen in FIG. 15B, particularly at enlargement D, downwardly directed tooth 566 lies outwardly of the valley defined between teeth 312 and 314 and downwardly directed tooth 564 remains at a position inwardly of the valley defined between teeth 312 and 314, further outward displacement of slidable mounting assembly 122 causes both of downwardly directed teeth 564 and 566 to lie outwardly of the valley defined between teeth 312 and 314, as seen particularly in enlargement D in FIG. 15C. The momentary engagement and disengagement of downwardly directed tooth 564 respectively with and from the valley defined between teeth 312 and 314 twice slightly flexes the cantilevered catch tab 310 and provides a user-sensible resistance which indicates to the user that the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is being fully opened.

From a comparison of FIG. 15C with FIGS. 15A/1 and 15A/2, it is seen that whereas in the first operative orientation shown in FIG. 15A/2, particularly at enlargements E & F, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 adjacent rounded end 563, in the third operative orientation shown in FIG. 15C, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 adjacent rounded end 562. It is appreciated that the engagement of pin 185 with elongate cut out 561 is operative to limit the extension of the slidable mounting assembly 122 relative to the remainder of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C along axis 108 (FIG. 1A) in a direction defined by arrows 710 and 720.

Reference is now made to FIG. 15D, which shows insertion of a mobile communicator 101 into the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C in the third operative orientation.

Reference is now made to FIG. 15E, which shows partial retraction of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C in a fourth operative orientation in engagement with a mobile communicator 101 in which the slidable top housing portion 106 and slidable mounting assembly 122 are slightly retracted from their operative orientation shown in FIGS. 15C and 15D, typically defining a separation between adjacent surfaces 700 and 702 of the slidable top housing portion 106 and the main top housing portion 104 respectively, typically approximately 3 mm.

It is seen from a comparison of FIG. 15E with FIG. 15C that whereas in the third operative orientation of FIG. 15C, the slidable engage/disengage point of sale terminal 100 is fully opened by the user grasping the top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 720, in the fourth operative orientation of FIG. 15E, the slidable mounting assembly 122 is partially retracted by the user grasping the top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 730, which is opposite to the direction indicated by arrow 720.

Whereas in the third operative orientation shown in FIG. 15C, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 504 and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof, in the fourth operative orientation shown in FIG. 15E, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 intermediate ends 504 and 506 thereof and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) intermediate rounded ends 614 and 616 thereof. It is also seen that base portion 610 of first slidable pin element 410 (FIGS. 10A-10D) is located in recess 514 formed in base portion 400 intermediate inward end 516 and outward end 518 thereof.

Correspondingly, whereas in the third operative orientation shown in FIG. 15C, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 524 and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 644 thereof, in the fourth operative orientation shown in FIG. 15E, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 intermediate rounded ends 524 and 526 thereof and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) intermediate rounded ends 644 and 646 thereof. Second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) is located in recess 534 formed in base portion 400 intermediate inward end 535 and outward end 536 thereof.

Whereas, as seen in FIG. 15C, particularly at enlargement D, both of downwardly directed teeth 564 and 566 lie outwardly of the valley defined between teeth 312 and 314, inward displacement of slidable mounting assembly 122 to the orientation shown in FIG. 15E causes downwardly directed tooth 564 to momentarily engage and disengage the valley defined between teeth 312 and 314 and thus twice slightly flexes the cantilevered catch tab 310. This provides a user-sensible resistance which indicates to the user that the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is being partially closed. In the orientation of FIG. 15E, downwardly directed tooth 564 lies inwardly of the valley defined between teeth 312 and 314 and downwardly directed tooth 566 remains outwardly of the valley defined between teeth 312 and 314.

Reference is now made to FIG. 15F, which shows full retraction of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C to the first operative orientation (FIGS. 15A/1 and 15A/2). This operative orientation is realized by by the user grasping the top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 740, which is parallel to the direction indicated by arrow 730 (FIG. 15E).

In the operative orientation shown in FIG. 15F, the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is in engagement with mobile communicator 101 and the adjacent surfaces 700 and 702 of the slidable top housing portion 106 and the main top housing portion 104 respectively are in touching engagement. In this operative orientation, the mobile communicator 101 is hugged in sockets 114 and 116 (FIGS. 4A-5B) of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C.

It is seen that ends 602 and 632 of respective cylindrical portions 600 and 630 of respective slidable pin elements 410 and 420 are in engagement with an outer edge surface of the mobile communicator 101.

It is also seen that connector 682 is inserted into operative engagement with a corresponding internal connector socket 750 of the mobile communicator 101.

It is additionally seen that base portion 610 of first slidable pin element 410 (FIGS. 10A-10D) remains located at the outward end 518 of recess 514 formed in base portion 400. Correspondingly, second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) remains located at the outward end 536 of recess 534 formed in base portion 400.

Whereas, as seen in FIG. 15E, particularly at enlargement D, downwardly directed tooth 566 lies outwardly of the valley defined between teeth 312 and 314 and downwardly directed tooth 564 is at a position inwardly of the valley defined between teeth 312 and 314, further inward displacement of inwardly-directed extension portion 560 to the first operative orientation shown in FIG. 15F, as particularly seen at enlargement D, causes downwardly directed tooth 566 to lie in the valley defined between teeth 312 and 314 and causes downwardly directed tooth 564 to lie inwardly thereof along cantilevered catch tab 310. The engagement of downwardly directed tooth 566 with the valley defined between teeth 312 and 314 slightly flexes the cantilevered catch tab 310 and provides a user-sensible resistance which indicates to the user that the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is being fully closed.

Reference is now made to FIG. 15G, which shows locking of the latch of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C, which prevents inadvertent disengagement of the mobile communicator 101 from the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C.

As seen in FIG. 15G, particularly in enlargement B, when finger engagement protrusion 692 of slidable latch element 132 (FIGS. 14A-14C) is positioned in a locking position, latch operating lever portion 694 lies in a locking position in latch travel slot 344 blocking slidable mounting assembly latchable protrusion travel path recess 346 and thus preventing outward displacement of generally U-shaped protrusion 550 (FIG. 9B) therealong and thus prevents slidable displacement of slidable mounting assembly 122 relative to main mounting element 120, which could allow disengagement of the mobile communicator 101 from the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C. The slidable latch element 132 may be retained in the locking position by engagement of screw 698 therewith via screw socket 168, formed in bottom housing portion 102.

Reference is now made to FIGS. 15H and 15I, which respectively show reading of a magnetic stripe card and of a smart card by the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C. Reference is also made to FIG. 15J which illustrates operation of optional bar code reader 136 (FIGS. 2A & 2B)

Reference is now made to FIG. 15K, which shows unlocking of the latch of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C, which permits disengagement of the mobile communicator 101 from the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C.

As seen in FIG. 15K, particularly in enlargement B, when finger engagement protrusion 692 of slidable latch element 132 (FIGS. 14A-14C) is positioned in a non-locking position, latch operating lever portion 694 lies in a non-locking position in latch travel slot 344 not blocking slidable mounting assembly latchable protrusion travel path recess 346 and thus not preventing outward displacement of generally U-shaped protrusion 550 therealong and thus permitting slidable displacement of slidable mounting assembly 122 relative to main mounting element 120, which allows disengagement of the mobile communicator 101 from the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C.

Reference is now made to FIGS. 15L/1 and 15L/2, which are together a simplified illustration of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C in a fifth operative orientation. As seen in FIGS. 15L/1 and 15L/2, in the fifth operative orientation, the slidable top housing portion 106 and slidable mounting assembly 122 are extended outwardly relative to main top housing portion 104 and to bottom housing portion 102 to a fifth extent, typically defining a separation between adjacent surfaces 700 and 702 of the slidable top housing portion 106 and the main top housing portion 104 respectively, typically approximately 3 mm.

It is seen from a comparison of FIGS. 15L/1 and 15L/2 with FIG. 15K that whereas in FIG. 15K, in the first operative orientation, the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is closed, in the fifth operative orientation of FIGS. 15L/1 and 15L/2, the slidable engage/disengage point of sale terminal 100 is partially opened by the user grasping the slidable top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 760.

It is a particular feature of the fifth operative orientation that the mobile communicator 101 remains fully engaged with the slidable mounting assembly 122 and is fully seated in first housing portion socket 114 of the slidable top housing portion 106, fixed to slidable mounting assembly 122 and is partially disengaged from the second housing portion socket 116 of the main top housing portion 104.

It is seen that ends 602 and 632 of respective cylindrical portions 600 and 630 of respective first and second slidable pin elements 410 and 420 remain in engagement with the outer edge surface of the mobile communicator 101 and that base portion 610 of first slidable pin element 410 (FIGS. 10A-10D) remains located at the outward end 518 of recess 514 formed in base portion 400. Correspondingly, second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) remains located at the outward end 536 of recess 534 formed in base portion 400.

As seen further in FIG. 15L/2, particularly where slidable top housing portion 106, slidable pins elements 410 & 420, connector support element 430 and connector assembly 440 are removed, and specifically at enlargements E & F, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 intermediate rounded ends 562 and 563 thereof.

Reference is now made to FIGS. 15M/1 and 15M/2, which is a simplified illustration of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C in the third operative orientation in which the slidable top housing portion 106 and slidable mounting assembly 122 are extended fully outwardly relative to main top housing portion 104 and to bottom housing portion 102, typically defining a separation between adjacent surfaces 700 and 702 of the slidable top housing portion 106 and the main top housing portion 104 respectively, typically approximately 8 mm.

It is seen that connector 682 is fully disengaged from corresponding internal connector socket 750 of the mobile communicator 101.

It is seen from a comparison of FIGS. 15M/1 and 15M/2 with FIGS. 15L/1 and 15L/2 that whereas in FIGS. 15L/1 and 15L/2, in the fifth operative orientation, the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is partially open, in the third operative orientation of FIGS. 15M/1 and 15M/2, the slidable engage/disengage point of sale terminal 100 is fully opened by the user grasping the top housing portion 106 with one hand and the bottom housing portion 102 with his other hand, and sliding the slidable mounting assembly 122 relative to the bottom housing portion 102 in the direction indicated by arrow 770, which is identical to the direction indicated by arrow 760 (FIG. 15L/1).

Whereas in the fifth operative orientation shown in FIGS. 15L/1 and 15L/2, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof, in the third operative orientation shown in FIGS. 15M/1 and 15M/2, pin 300 of main mounting element 120 (FIG. 6A) is located in elongate cut out 502 of base portion 400 of slidable mounting assembly 122 adjacent rounded end 504 and is also simultaneously located in elongate slot 612 of first slidable pin element 410 (FIGS. 10A-10D) adjacent rounded end 614 thereof.

Correspondingly, whereas in the fifth operative orientation shown in FIGS. 15L/1 and 15L/2 pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 at an intermediate location therealong and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 644 thereof, in the third operative orientation shown in FIGS. 15M/1 and 15M/2, pin 302 of main mounting element 120 (FIG. 6A) is located in elongate cut out 522 of base portion 400 of slidable mounting assembly 122 adjacent end 524 thereof and is also simultaneously located in elongate slot 642 of second slidable pin element 420 (FIGS. 11A-11D) adjacent rounded end 644 thereof. Second base portion 640 of second slidable pin element 420 (FIGS. 11A-11D) is now located at the inward end 535 of recess 534 formed in base portion 400.

Whereas, as seen in FIGS. 15L/1 and 15L/2, particularly at enlargement D, downwardly directed tooth 566 lies outwardly of the valley defined between teeth 312 and 314 and downwardly directed tooth 564 is at a position inwardly of the valley defined between teeth 312 and 314, further outward displacement of slidable mounting assembly 122 causes both of downwardly directed teeth 564 and 566 to lie outwardly of the valley defined between teeth 312 and 314, as seen particularly in enlargement D in FIGS. 15M/1 and 15M/2. The momentary engagement and disengagement of downwardly directed tooth 564 respectively with and from the valley defined between teeth 312 and 314 twice slightly flexes the cantilevered catch tab 310 and provides a user-sensible resistance which indicates to the user that the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C is being fully opened.

As further seen in FIG. 15M/2, specifically at enlargements E & F, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 adjacent rounded end 562 thereof.

From a comparison of FIG. 15M/2 with FIG. 15L/2, it is seen that whereas in the fifth operative orientation shown in FIG. 15L/2, particularly at enlargements E & F, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 intermediate rounded ends 562 and 563 thereof, in the third operative orientation shown in FIG. 15M/2, pin 185 of main top housing portion 104 is located within elongate cut out 561 of base portion 400 adjacent rounded end 562. It is appreciated that the engagement of pin 185 with elongate cut out 561 is operative to limit the extension of the slidable mounting assembly 122 relative to the remainder of the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C along axis 108 (FIG. 1A) in a direction defined by arrows 760 and 770.

Reference is now made to FIG. 15N, which is a simplified pictorial illustration of disengagement of the mobile communicator 101 from the slidable engage/disengage point of sale terminal 100 of FIGS. 1A-14C when it is in the third operative orientation.
